Segmented Fuel Pump Cover for Outlet Protection and Hose Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional single-piece fuel pump protective covers are difficult to attach and do not provide sufficient protection for fuel pumps and their elements.
Innovation Solution
A fuel pump cover comprising two separable cover members, with a first cover member attaching to the fuel tank and a second cover member removably attaching to the first, providing comprehensive protection for multiple fuel pump outlets and facilitating easy attachment and removal of fuel hoses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-piece fuel pump protective cover is used, then the structure is simple, but it is difficult to attach and does not provide sufficient protection for fuel pump outlets
Solution Approach 1:
The fuel pump protective cover is divided into multiple separate cover members (first cover member, second cover member, third cover member) instead of using a single-piece design. Each cover member can be independently attached to protect specific fuel pump outlets, providing better protection while maintaining attachment feasibility. The segmentation allows each cover member to be optimally sized and shaped for its specific protective function.
2Ease of manufacture
If a single-piece fuel pump protective cover is used, then the manufacturing process is simple, but it does not allow for individual access to fuel hoses
Solution Approach 1:
The cover is segmented into multiple removable cover members that can be independently detached. This allows individual access to specific fuel hoses by removing only the relevant cover member rather than disassembling the entire cover structure. The segmentation maintains manufacturing simplicity while dramatically improving operational accessibility.
Solution Approach 2:
The cover members are designed to be dynamically removable and reattachable rather than fixed permanently. This dynamic design allows the cover system to adapt between two states: fully assembled for protection and partially disassembled for maintenance access. The attachment features enable easy attachment and detachment of individual cover members.
3Device complexity
If a single-piece fuel pump protective cover is used, then the component count is low, but it provides insufficient protection for multiple outlets
Solution Approach 1:
The protective cover system is segmented into multiple specialized cover members, each designed to protect specific fuel pump outlets. This segmentation allows comprehensive protection of all outlets while maintaining a relatively low component count compared to alternative designs. Each cover member can be optimally configured for its specific protective function, reducing overall risk to individual outlets.
Solution Approach 2:
Each cover member is designed with local quality optimized for its specific protective function. The first cover member protects the first outlet, the second cover member protects the second outlet, and the third cover member protects the third outlet. This localized optimization provides superior protection for each outlet compared to a generic single-piece cover design.

AI summary
A fuel pump cover includes a first cover member and a second cover member. The first cover member has an attachment flange configured to attach to a surface of a fuel tank, a cover part coupled to the attachment flange and configured to cover a first fuel pump outlet to a fuel pump, and an attachment feature. The second cover member is configured to be removably attached to the attachment feature, and configured to cover a second fuel pump outlet to the fuel pump.
